In a lab experiment, the decay of a radioactive isotope is being observed. At the beginning of the first day of the experiment the mass of the substance was 1300 grams and mass was decreasing by 14% per day. Determine the mass of the radioactive sample at the beginning of the 11th day of the experiment. Round to the nearest tenth (if necessary).

after x days, the amount left is
f(x) = 1300 * 0.86^x
so now just find f(10)
f(x) = 1300 * 0.86^x
so now just find f(10)
